Patent number: 10303003Abstract: A method of manufacturing a liquid crystal display device including a TFT substrate with display and peripheral regions. The display region has pixels each having a pixel electrode and a TFT. A counter substrate opposes the TFT substrate and has a color filter formed at a position corresponding to a position at which the pixel electrode is formed above the TFT substrate. The method includes coating, outside of the display region of the TFT substrate, a second alignment film in the shape of a frame, and coating, in the display region, a first alignment film that dries more slowly than the second alignment film. The first and second alignment films are in contact, and the second alignment film is thicker than the first alignment film.Type: GrantFiled: February 12, 2018Date of Patent: May 28, 2019Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Tomoyuki Shiromoto, Toshirou Iwata, Rai Yang, Shinichi Soto

Patent number: 8514356Abstract: In a liquid crystal display device small in the size and having a narrow frame, an alignment film can be coated by ink jet printing, by coating a rapidly drying peripheral alignment film 109 in the shape of a frame to a TFT substrate 100 having a display region having pixel electrode 107 and a peripheral region thereof by ink jet printing, and then coating a display region alignment film 108 drying slower but excellent in the leveling effect by ink jet printing. While the display region alignment film 108 dries slowly, since the peripheral alignment film 109 formed to the periphery functions as a stopper, the shape of the alignment film can be defined accurately, thereby enabling to prevent lowering of the adhesion of the seal member 20 under the effect of the alignment film. This can be applied also on the side of the counter substrate 200.Type: GrantFiled: January 11, 2011Date of Patent: August 20, 2013Assignees: Hitachi Displays, Ltd., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Tomoyuki Shiromoto, Toshirou Iwata, Rai Yang, Shinichi Soto

Patent number: 6900875Abstract: In a process for forming an alignment film on a substrate that is used for a liquid crystal display, a coating destined to be the alignment film is formed on one surface of the substrate, and a gas flow is formed by a nozzle on a surface side on which the coating is formed. By thus implementing, an uniform alignment film can be formed on the substrate for use in the liquid crystal display.Type: GrantFiled: August 19, 2002Date of Patent: May 31, 2005Assignee: Hitachi, Ltd.Inventors: Keiko Nakano, Hirotaka Imayama, Shigeki Matsuda, Toshirou Iwata, Masahiro Yamada
